1,011,180. ecu t of 1mm Patent Patented Dec. 12, 1911. Application med February 24, 1911. Serial in. mesa To all whom it may broken away. Fig. 3 is a perspective view Be it known that I, JOHN W. FREEMAN, of a portion of the bed of t e hoist. Fig. 4 a citizen of the United States, residing at is a side elevation of the bed of the hoist. Joplin, in the county ofJasper and State of The hoist includes a bed 1 having located Missouri, have invented a new and useful upoirits to and in the vicinity of one of 60 Gearing, of which the following is a speciits side ges bearigg brackets 2. The fication. brackets 2 are in fix positions upon the This invention has relation to hoists of bed 1 and a drum shaft 3 is ournaled in the the single reduction t e and consists in the upper ends of the said bracliets. A drum 4 novel construction an arrangement of its mounted upon the shaft 3 and a gear parts as hereinafter shown and described. wheel 5 is fixed to the said shaft.

The object of the invention is to provide The bearing brackets 6 are also located a gear hoist preferably employing an elecp n the 11 per side of the bed 1 but may trio motor as a prime mover and which inbe adiust and secured in one of several 16 cludes a drivin pinion mounted upon the positions upon the said bed. A motor frame motor shaft and a driven gear wheel mesh- 7 is also mounted upon the upper side of the ing with said pinion and mounted upon the bed 1 and may be adiusted and fixedly sewinding drum h ft, M ns i ov d d f r cured in one of severa positions. The posishifting the motor, its shaft and its su tions at which the motor frame 7 may be 20 portin brackets together with the pinion Secured p n the bed 1 will register t upon t e bed of the hoist and securing the e sely 0 the machine with the positions at' same in adjusted position whereby a mion i h the brackets 6 may be secured upon of small size ma be removed from t e enthe 1- In the present invention the e shaft and a arger pinion substituted in F c 18 n the f rm of an elec ri m r u 26 1ts stead or conversely a large inion may it .18 to be understood that another f0I ID 0f .80
